Abstract

A multi-band communication device includes a first wireless signal processing circuit, a second wireless signal processing circuit, an antenna switch module (31), a first antenna unit (30) and a second antenna unit (33). The first wireless signal processing circuit is used for operating multiple first band signals. The second wireless signal processing circuit is used for operating multiple second band signals. The antenna switch module (31) is in communication with the first wireless signal processing circuit and the second wireless signal processing circuit for switching the first band signals and a first portion of the second band signals. The first antenna unit (30) is in communication with the antenna switch module (31). The second antenna unit (33) is in communication with the second wireless signal processing circuit.
